Dear cs'ers, I recently had the opportunity to play with a spectrophotometer.Using the instruction book procedures gave the following readings:
I took readings at wavelengths for blue(470nm),green(555nm),yellow(585nm),orange(610nm) and red(650nm).The results indicated a figure for Absorption(A) and Transmission(T) %. Blue;A=0.143 T=71.8 ,Green;A=0.136 T=73.2 Yellow;A=0.118 T=75.9 Orange;A=0.115 T=76.8 Red;A=0.093 T=80.7 My question for those familiar with this apparatus is; What particle size could be ascertained from these results? My cs production method uses 27v and halts at 8mA using spiral shaped electrodes spaced 25mm apart.Results are a clear solution (no colour) but a slight tyndall effect observable via high power(1w) leds Thank you for taking time to reply. pete ********************************************************************** This message is intended for the addressee named and may contain privileged information or confidential information or both.
